Graphing an Inequality

Property To graph an inequality such as $y \geq f(x)$ or $y \leq f(x)$, enter the function $f(x)$ into the Y= editor and change the line style to the 'greater than' (shading above) or 'less than' (shading below) symbol.

To graph $y \geq 5 x$, enter $y = 5 x$ and change the line style to the 'greater than' symbol. To visualize the solution to $y \leq x^2$, enter $y = x^2$ and change the line style to the 'less than' symbol.

Graphing an inequality is like drawing a boundary and then shading in all the possible solutions. Your calculator does the heavy lifting! Just enter the boundary equation, then select the 'greater than' symbol to shade above the line or the 'less than' symbol to shade below it. It visually shows every single point that makes the inequality true.
